Detecting dark objects in the Solar System with Gravitational Wave observatories

TL;DR

This paper explores how gravitational wave observatories can detect dark objects like primordial black holes or dark matter clumps in the solar system by analyzing the perturbations they cause on test masses, highlighting DECIGO's potential.

Contribution

It introduces a method to detect dark objects in the solar system via gravitational wave signals and assesses the capabilities of current and future GW observatories.

Findings

DECIGO can detect dark matter clumps and primordial black holes in the mass range 10^7 to 10^{11} grams.

Gravitational wave perturbations provide a new way to probe dark objects in the solar system.

Current GW observatories have limited sensitivity, but future detectors like DECIGO show promising detection prospects.

Abstract

Dark objects streaming into the solar system can be probed using gravitational wave (GW) experiments through the perturbations that they would induce on the detector test masses. In this work, we study the detectability of the resulting gravitational signal for a number of current and future GW observatories. Dark matter in the form of clumps or primordial black holes with masses in the range $10^7$-$10^{11}\,\rm{g}$ can be detected with the proposed DECIGO experiment.
